Background: Oma1 is a conserved membrane-bound protease that forms a high molecular mass complex.
Results: Oma1 activity is induced by stress stimuli and required for survival. The activation is linked to changes in Oma1 oligomer stability and involves its C-terminal region.
Conclusion: Oma1 function is activated by mitochondrial stress and is important for stress tolerance.
Significance: Novel insights into Oma1 function and a potential stress activation mechanism are provided.
